Abstract
INTRODUCTION The aim of this study was to generate virtual Magnetic resonance (MR) from computed tomography (CT) using conditional generative adversarial networks (cGAN). METHODS We selected examinations from 22 adults who obtained their CT and MR lumbar spine examinations. Overall, 4 examinations were used as test data, and 18 examinations were used as training data. A cGAN was trained to generate virtual MR images from the CT images using the corresponding MR images as targets. After training, the generated virtual MR images from test data in epochs 1, 10, 50, 100, 500, and 1000 were compared with the original ones using the mean square error (MSE) and structural similarity index (SSIM). Additionally, two radiologists also performed qualitative assessments. RESULTS The MSE of the virtual MR images decreased as the epoch of the cGANs increased from the original CT images: 8876.7 ± 1192.9 (original CT), 1567.5 ± 433.9 (Epoch 1), 1242.4 ± 442.0 (Epoch 10), 1065.8 ± 478.1 (Epoch 50), 1276.1 ± 718.9 (Epoch 100), 1046.7 ± 488.2 (Epoch 500), and 1031.7 ± 400.0 (Epoch 1000). No considerable differences were observed in the qualitative evaluation between the virtual MR images and the original ones, except in the structure of the spinal canal. CONCLUSION Virtual MR lumbar spine images using cGANs could be a feasible technique to generate near-MR images from CT without MR examinations for evaluation of the vertebral body and intervertebral disc. IMPLICATIONS FOR PRACTICE Virtual MR lumbar spine images using cGANs can offer virtual CT images with sufficient quality for attenuation correction for PET or dose planning in radiotherapy.

Abstract
In this study, we examined the effect of mitomycin C (MMC) treatment on graft survival and evaluated its efficacy in immunomodulation of islet graft for transplantation. Male WS rats were used as islet donors and streptozotocin-induced diabetic C57BL/6 mice as recipients. The isolated islets were treated with MMC at concentrations of 0, 0.1, 1, 3.2, 10, 32, 100, 320, and 1000 μg/mL for 30 min, and were cultured for 20 h. Then, 300–400 islets were transplanted into the renal subcapsular space of diabetic mice. Significant prolongation of graft survival was obtained when the islets were treated with MMC at a concentration of 10, 32, or 100 μg/mL (MST 23 ± 7.4, 17.5 ± 5.4, 29.6 ± 9.7 days: p < 0.003, p < 0.012, p < 0.001, respectively, vs. 12.3 ± 2.7 days for culturing alone). Islets treated with MMC at a concentration of 320 μg/mL or more failed to restore normoglycemia in the diabetic recipient mice after transplantation. Viability of islets incubated with doses up to 100 μg/mL, assessed under the confocal microscope after propidium iodide and Hoechst 33342 staining, was maintained well comparable to that of freshly isolated islets, while those treated at 320 μg/mL was significantly decreased. Thus, a therapeutic window for MMC efficacy was found at concentrations from 10 μg/mL to 100 μg/mL. This modality is simple and effective and underlying molecular mechanisms need to be determined in the future.

Abstract
Purpose: To clarify the Doppler sonographic features of the lingual artery in normal subjects and to evaluate those of patients with cancer of the tongue. Material and Methods: Sixty-seven volunteers and 12 patients with cancer and/or leukoplakia of the tongue were examined with an intraoral sonographic probe. The visibility of the deep lingual artery was determined on transverse and anteroposterior images. On the transverse images, the vascular index, which was defined as the number of colored pixels, was measured on bilateral lingual arteries. Thereafter, the degree of symmetry was evaluated for normal subjects and patients. Results: In normal subjects, between younger and older volunteers, there were no significant differences in visibility of the trunk but differences were found between the two groups for the dorsal branches. The vascular indices of the right and left sides were not different. The characteristic Doppler sonographic feature was vasculature in and around the tumors in the patients with cancer of the tongue. The symmetry indices of the cancer patients were significantly different from those of normal subjects. Conclusion: Doppler sonography should be an important procedure for evaluation of tongue neoplasms.

Abstract
The number of DNP group-bearing lymphocytes in the regional lymph node, thoracic duct and peripheral blood was determined at various time intervals after painting normal guinea pigs with DNCB by the immunofluorescent method using anti-DNP antibody. The incidence of such cells in the regional node was maximal at 12 hours whereas in the thoracic duct and peripheral blood the maximum incidence was found at 0.1-2 hours after painting. Unreacted DNCB was demonstrated in both the thoracic lymph duct and the blood at least for 12 or 24 hours respectively following exposure to DNCB. The authors therefore suggest that DNCB reacts directly in vivo with the lymphocyte cell membrane of guinea pig following epicutaneous application of the chemical.

Abstract
BACKGROUND We evaluated the efficacy and safety of S-1 plus oxaliplatin (SOX) as an alternative to cisplatin plus S-1 (CS) in first-line chemotherapy for advanced gastric cancer (AGC). PATIENTS AND METHODS In this randomized, open-label, multicenter phase III study, patients were randomly assigned to receive SOX (80-120 mg/day S-1 for 2 weeks with 100 mg/m(2) oxaliplatin on day 1, every 3 weeks) or CS (S-1 for 3 weeks with 60 mg/m(2) cisplatin on day 8, every 5 weeks). The primary end points were noninferiority in progression-free survival (PFS) and relative efficacy in overall survival (OS) for SOX using adjusted hazard ratios (HRs) with stratification factors; performance status and unresectable or recurrent (+adjuvant chemotherapy) disease. RESULTS Overall, 685 patients were randomized from January 2010 to October 2011. In per-protocol population, SOX (n = 318) was noninferior to CS (n = 324) in PFS [median, 5.5 versus 5.4 months; HR 1.004, 95% confidence interval (CI) 0.840-1.199; predefined noninferiority margin 1.30]. The median OS for SOX and CS were 14.1 and 13.1 months, respectively (HR 0.958 with 95% CI 0.803-1.142). In the intention-to-treat population (SOX, n = 339; CS, n = 337), the HRs in PFS and OS were 0.979 (95% CI 0.821-1.167) and 0.934 (95% CI 0.786-1.108), respectively. The most common ≥grade 3 adverse events (SOX versus CS) were neutropenia (19.5% versus 41.8%), anemia (15.1% versus 32.5%), hyponatremia (4.4% versus 13.4%), febrile neutropenia (0.9% versus 6.9%), and sensory neuropathy (4.7% versus 0%). CONCLUSION SOX is as effective as CS for AGC with favorable safety profile, therefore SOX can replace CS. CLINICAL TRIAL NUMBER JapicCTI-101021.

Abstract
BACKGROUND Quantification of the serum level of BK virus is used as a surrogate marker for the early onset of BK virus nephropathy. However, little is known about the diagnostic value of the urine level of BK virus for nephropathy or the relationship between the serum and urine viral load. We investigated the correlation between urine and serum BK virus levels after renal transplantation. METHODS From November 2008 to August 2013, a total of 270 renal transplant patients who were followed at our institution were included in this study. Urine and serum were collected simultaneously. BK virus levels were quantified in 894 urine and serum samples using a real-time polymerase chain reaction assay. RESULTS BK virus was detected in 178 urine samples and 36 serum samples. Among the BK virus-positive urine subjects, the positive predictive value for viral detection in the serum was 9% (13/147) when the urinary virus level was <10(7) copies/mL and 74% (23/31) when the urinary virus was ≥ 10(7) copies/mL. Serum BK viral levels were ∼2-3 log units lower than those in urine. CONCLUSIONS BK virus was detected more frequently in serum when present in urine at ≥ 10(7) copies/mL after renal transplantation.

Abstract
BACKGROUND Little is known about the timing of polyomavirus reactivation and its presence in urine after renal transplantation. The purpose of this study was to investigate the prevalence of positive polyomavirus in urine at various time points after renal transplantation. METHODS From November 2008 to August 2013, 279 renal transplant patients from our institution were included in this study. One urine sample was collected at 0-3, 4-6, 7-12, 13-24, 25-60, and ≥ 61 months after renal transplantation. A total of 394 urine samples were assessed for the presence of the BK and JC viruses with the use of a real-time polymerase chain reaction assay. RESULTS BK virus was detected in the urine of one-third of patients during the first 6 months. Thereafter, the positivity rate decreased gradually to 12% >5 years after transplantation. The positivity rate for the JC virus in urine was 33%-49% regardless of the post-transplantation phase. CONCLUSIONS BK virus was detected more frequently in urine during the early phase after renal transplantation, whereas the JC virus was detected more consistently.

Abstract
A 48-year-old male presented with para-aortic lymph node metastases after surgical resection of a clear cell renal cell carcinoma. After first-line treatment with interferon alpha-2b, he was started on pazopanib and lapatinib. Blood pressure was well controlled with temocapril and amlodipine. Treatment had to be stopped 4 years and 8 months after initiation due to overt proteinuria. Then, sunitinib was started as third-line treatment. During the second cycle of sunitinib, he died due to a Stanford type A aortic dissection. Acute aortic dissection could be an adverse event associated with the long-term use of antiangiogenic tyrosine kinase inhibitors.

Abstract
Human induced pluripotent stem cell (hiPSC)-derived neurons may be effectively used for drug discovery and cell-based therapy. However, the immaturity of cultured human iPSC-derived neurons and the lack of established functional evaluation methods are problematic. We here used a multi-electrode array (MEA) system to investigate the effects of the co-culture of rat astrocytes with hiPSC-derived neurons on the long-term culture, spontaneous firing activity, and drug responsiveness effects. The co-culture facilitated the long-term culture of hiPSC-derived neurons for >3 months and long-term spontaneous firing activity was also observed. After >3 months of culture, we observed synchronous burst firing activity due to synapse transmission within neuronal networks. Compared with rat neurons, hiPSC-derived neurons required longer time to mature functionally. Furthermore, addition of the synapse antagonists bicuculline and 6-cyano-7-nitroquinoxaline-2,3-dione induced significant changes in the firing rate. In conclusion, we used a MEA system to demonstrate that the co-culture of hiPSC-derived neurons with rat astrocytes is an effective method for studying the function of human neuronal cells, which could be used for drug screening.

Abstract
A 30-year-old man presented with micturition pain and was diagnosed with a submucosal tumor in the right wall of the bladder with metastasis to the right obturator lymph node. Transurethral resection led to a diagnosis of invasive malignant pheochromocytoma. Radical cystectomy, neobladder reconstruction and bilateral iliac lymph node dissection were performed. Genetic analysis revealed succinate dehydrogenase B-associated hereditary pheochromocytoma/paraganglioma syndrome. 10 months after the operation, he had no evidence of recurrence.

Abstract
Blood lead levels (BLLs) of 188 pediatric patients were measured and their parents were queried as to the smoking style in their home. Their mean BLL was 3.16 μg/dl, which was among the lowest levels in the world, and none of them had levels of over 10 μ g/dl. Preschool children ( 1 to 6 years of age) with parents who smoked in the same room had a significantly higher BLL (mean; 4.15 μ g/dl) than those with parents who never smoked (mean; 3.06 μ g/dl) (P<0.01). However, the mean BLL of school children (6 to 15 years of age) with parents who smoked in the same room was not significantly different from that of school children with parents who never smoked. Passive smoking caused an increase of the BLL only in preschool children in Japan. This is probably because preschool infants spend much more time with their parents and have much more contact with passive smoking than school children and, additionally young infants have a limited ability to excrete lead from the body.

Abstract
The worldwide shortage of deceased-donor kidneys for transplantation has become a serious issue in the past decade, leading to study of marginal donors. However, both the availability and the utility of kidneys from deceased donors are still unclear. The aim of the present study was to evaluate another method to estimate donor kidney function rather than using donor creatinine (Cr). We studied 129 recipients of deceased-donor kidneys from Maastriche donor categories III and IV. We analyzed donor Cr levels before death and recipient Cr levels at 1 year after transplant, as well as estimated glomerular filtration rates (eGFR). There was no significant difference in donor Cr levels at admission to the hospital and before death according to eGFR at 1 year after transplantation: <30 mL/min/1.73 m(2) versus ≧30 mL/min/1.73 m(2). However, recipients whose donors showed lower average eGFR levels on admission displayed better renal function at 1 year after transplant (P = .025). In conclusion, donor Cr levels before death was a less useful measurement to relate to recipient renal function; eGFR provided a better index.

PURPOSE The potential for introducing transmissible spongiform encephalopathy (TSE) into islet cells was indicated by recognizing that Liberase HI is isolated from Clostridium histolyticum grown in media containing brain-heart infusion broth. A national team within the Japanese Pancreas and Islet Transplantation Association implemented an islet transplantation program in Japan using Liberase HI. The program comprised 65 islet isolations from non-heart-beating donors and 34 transplants into 18 patients. Herein, we have summarized how the Association followed these recipients over the long term. PROCEDURES We established an ad hoc committee to follow recipients transplanted with islets isolated using Liberase HI after becoming informed of the associated dangers of using this enzyme. We also stopped islet transplantations using Liberase. The committee addressed the major concerns of the risk of the collagenase being contaminated with TSE and of the recipient follow-up. All recipients were examined by diffusion MRI and EEG and then scheduled for evaluation and follow-up by specialists in Creutzfeldt-Jakob disease (CJD). Bioassays of bovine spongiform encephalopathy prions in the enzyme proceeded using knock-in mice expressing bovine prion protein. These assays could detect contaminating prions at a dilution of 1 × 10(4). After inactivating its collagenase activity, Liberase HI was injected into the abdominal cavities of knock-in mice. Four months later, prion infectivity in Liberase HI was evaluated by immunohistochemical staining and Western blotting of spleen homogenates using anti-prion protein antibodies. MAIN FINDINGS Western blotting and immunohistochemical staining did not detect prions in Liberase HI. Diffusion MRI and EEG evaluations performed by CJD specialists confirmed that none of the transplanted recipients had CJD. CONCLUSIONS Three years of follow-up revealed that none of the Japanese recipients of islet transplants developed CJD. Prion bioassays showed that the Liberase HI used to isolate islets for transplantation was free of infectious TSE prions.

Abstract
ABSTRACTThe structural and optical properties of CdS/CdTe(S) interface region of 2-μm thick CdS/CdTe solar cells have been studied in conjunction with photovoltaic performances of the solar cells. The properties are found to be crucially influenced by the annealing temperature and oxygen concentration of the CdCl2 treatment. An increase in VOC and F.F. found in the solar cells with the CdCl2 treatment at < 360°C is interpreted as due to suppression of interdiffusion of sulfur and tellurium at the CdS/CdTe(S) interface. On the other hand, the electromodulated photoluminescence with UV light excitation (UVE-EMPL) study reveals that the increasing VOC due to increasing oxygen concentration to 5% is likely to be caused by an increase in the built-in electric field in n+-CdTe1−xSx just adjacent to the CdS/CdTe(S) interface. As a result of the modification of the process parameters, we have achieved the conversion efficiency of 13.6% (VOC: 0.817V, JSC: 23.0 mA/cm2, F.F.: 0.725) using 2.3-μm thick PV active layer without anti-reflection coating.
